Implements a Ralph Kimball star schema for Claude Code user/device/session analytics, expressed as a Netflix UDA knowledge graph with projections to GraphQL, Avro, and Zod (TypeScript Agent SDK structured output). Domain model (domain_model.ttl): - 6 conformed dimensions: User (Type 2 SCD), Device, UserSurface, Model, Time, Tool - 3 fact tables: FactSession, FactToolUse, FactMessage - 7 enumerations as controlled vocabularies (PlanTier, SurfaceType, etc.) Projections: - schema.graphqls: Federation-ready GraphQL with @udaUri directives - schema.avro: Data Mesh Avro with udaUri and _pk_ attributes - kimball_dimensions.ts + kimball_facts.ts: Zod schemas for SDK output_format - mappings.ttl: UDA mappings connecting domain concepts to all three containers Informed by Netflix UDA blog (onepiece example schemas) and Anthropic's knowledge graph cookbook (entity/relation extraction patterns). https://claude.ai/code/session_01H5TrSfgA9x3vXTNYHnW4f8
